OK, I re-read your post. I don't think you have any problem with your adjusters! I think you need to change your flexible brake hoses!
What happens is this -- The hoses might look good on the outside, but they usually go bad from the inside out. They start out by getting soft inside. As the rubber gets soft it swells shut. When you mash on the pedal you generate a tremendous force on the brake fluid, and it pushes the hose open and lets fluid into the wheel cylinder to apply your brakes. Then, when you let off the brakes, the springs that pull your shoes back to the rest position can't generate enough pressure to force the hose open the other way . . . so the hose acts like a one way check valve. I didn't see to begin with that you said they shoes would back themselves off over night. When your brakes lock the next time, open the bleeder screw on one of your wheel cylinders . . . I'll bet you that fluid will squirt out and your shoes will back WAY off.
Change all four of the flexible hoses and flush all of the old fluid out of the system. After you bleed all the air out of the system, readjust your shoes.
